Damn, right. Each perl hash corresponds to multiple composite types, different
by the order of the type elements. Passing the typid sounds like a fair
requirement (and if it's missing we could assume that the order of columns in
composites doesn't matter to the caller).
Let me try implementing that as an XS interface to plperl_array_to_datum.
